Clean and Close

Clean and Close replaces the Clean Up button in your Download Manager window with a Clean And Close button that does just that – cleans completed, canceled and failed downloads from the download list and then closes the window. This add-on may not be compatible with other add-ons that modify the Download dialog, including the All-In-One sidebar add-on.
